It's strange that we don't test the ->speed_8mhz flag.  Do we even
need that flag?  It might be better to write it like this:

        if (dev->speed_32mhz) {
                ret = bus->ops->set_clockrate(dev, 32);
                 if (ret < 0) {
                        dev_err(&dev->dev,
                                "failed to switch to 32 MHz operation.\n");
                }
        }

The error message is not accurate in the original code because it
says 32 even if you tried to set it to 8.
